Digital Angle Gauge

Posted on June 14, 2016 The Engineer

Here’s a useful tool for the kit, a digital angle gauge/protractor. These use a silicon sensor to show the number of degrees the unit is out of level. Magnets are provided in the base, so the tool can attach to any ferrous surface. Power is provided by a single AAA

Eberspacher Controller & Remote

Posted on January 18, 2016January 18, 2016 The Engineer

The Eberspacher heaters can be controlled with a single switch, but it’s more convenient to have some temperature control & the option of a timer. Above is an ex-BT 701 series controller, with built in 7-day programmer. Being an ex-BT van version though, it’ll only switch the heater on for

Netgear GS308 Gigabit Switch

Posted on October 22, 2015 The Engineer

Here’s a new addition to the network, mainly to replace the ancient Cisco Catalyst 3500 XL 100MB switch I’ve been using for many years, until I can find a decently priced second hand commercial gigabit switch. Here’s the switch with some network connections on test. So far it’s very stable

Arduino Based SWR/PWR Meter – The Board

Posted on July 8, 2015February 25, 2017 The Engineer

I recently posted about a small analog SWR/Power meter I got from eBay, and figured it needed some improvement. After some web searching I located a project by ON7EQ, an Arduino sketch to read SWR & RF power from any SWR bridge. The Arduino code is on the original author’s

Marine Potable Water Management System

Posted on May 14, 2014 The Engineer

Having two separate water tanks on nb Tanya Louise, with individual pumps, meant that monitoring water levels in tanks & keeping them topped up without emptying & having to reprime pumps every time was a hassle. To this end I have designed & built this device, to monitor water usage
